Testnet push annoucement for 4/22

Hey everyone,

Heads up on testnet update tomorrow. We will be deploying a new version bf0e6e6 at 10am PST 4/22. This update includes several breaking changes (below), and the database will be wiped.

Breaking changes:

  1. Multi-currency and core modules (https://github.com/libra/libra/commit/10523d33b2d6b3b7ca6834b55498a3f192ff16e3)
  2. Move lang - allow the prologue & epilogue to have type arguments (https://github.com/libra/libra/commit/dfb5005f66227f5b0a6ef799b44c847551fee25a) and removal of max_stack_height from file format (https://github.com/libra/libra/commit/4a8d8d90fdd051b6952db33e3c0131e0bfd8b017)
  3. Crypto - rand & Fiat & Dalek update (https://github.com/libra/libra/commit/1c4cf2fae71c0a42ebfd67dfe5b6d0317078a114)
  4. Safety Rules - secure storage interface update
  5. Sorage Proto - TreeState and StartupInfo update

We expect the testnet to be down briefly during the update.


The network update is complete. testnet branch is also updated.

This time the testnet branch rust-rocksdb dependency is problematic.
Should use ba5f561 the submission.

I encountered the same problem, and I installed llvm and clang to fix it.
